Speaker grills protect the driver and finish the installation: replacement grills for ceiling and wall speakers whose originals have yellowed, dented, or gone missing, weather-resistant grills for outdoor and marine speakers, and the color and trim options that let an installed sound system disappear into the room instead of announcing itself.
Grills are model-specific - they mount to one speaker family's frame, so order by the exact speaker model on the ceiling, not by diameter alone. In refresh projects, new grills are the cheap way to make an aging but working speaker system look reinstalled, and paintable models let facilities match a renovation's ceiling color. Outdoor speakers should get the grill built for the exposure, since a corroded grill fails before the speaker behind it. Ordering a few spares with any large install covers the ones lost to ladders and repainting later.
